Abstract: 739,148. Cash registers. RIV-OFFICINE DI VILLAR PEROSA SOC. PER AZIONI. Dec. 23, 1953, No. 35790/53. Class 106 (1). Amount-setting levers of a cash register are each connected by a rod to an indicating drum and a type wheel which are rockable about the common axis of the setting levers. The lowest order setting lever 20, Fig. 4, is secured to a shaft 19. A corresponding type wheel 51 and a corresponding indicating drum segment 58 are also secured to the shaft 19. The other setting levers 23 are rockable about the shaft 19 and each carries a rod 56 parallel to that shaft and secured to the associated type wheel 57 and indicating segment 61 which are also rockable about the shaft 19. Each setting lever 23, Fig. 9, is toothed for co-operation with a corresponding detent lever 47. Ears 47a of these levers co-operate with slotted discs 13 on the mainshaft 10 to prevent operation of the machine if a setting lever is not properly set and to lock the setting levers during a machine operation. When the setting levers are readjusted prior to a new operation, a pin 65 in an arm 66 controlled by the levers 47 releases a spring-loaded slide 63, Fig. 8, carrying a shutter 62 which obscures the indicating segments 61. During the cycle, a cam restores the slide which is again latched by the pin 65. Urged by a spring to follow each setting lever 23 is a toothed segment 31. On rotation of the mainshaft 10, cams rock a frame 77 to engage the totalizer 78 with the segments, and then rock arms 71 carrying a bar 72 which returns the segments 31 to their zero positions and engages arcuate surfaces 31b thereon. The tens transfer mechanism is carried by a shaft 83 in the frame 77, which shaft is rotated by a partially-toothed gear 86, Fig. 5, near the end of the operation to effect any prepared transfers. The mainshaft 10 is rotated through gearing by a hand-crank fast on a shaft 4. The end position of the shaft is determined by the engagement of a finger 90 thereon with a lever 89 moved into the path of the finger by a cam stud 9a. To release the machine, the crank is first moved slightly in the reverse direction to allow the lever 89 to be rocked counterclockwise by a spring 98. Cams 92, 94 may be positioned by an inserted key to block a detent lever 91 engaging a gear on the shaft 4 and so to prevent operation of the machine, and to rock a lever 95 so as to permit insertion of a further key into a sleeve 82 on the totalizer shaft. Axial movement of this key moves a shutter 100 to allow the totalizer to be read whilst rotation of the key zeroizes the totalizer. Printing mechanism voucher-issuing.-The amount type wheels 57 each carry two sets of type for printing on record and voucher strips respectively. Three further type wheels 139, Fig. 12, are settable by pins 143, 144, 145, Fig. 11, in accordance with the date. A locking pin 146 is passed through holes 148 in these wheels. The record strip passes from a supply roll 160 to a take-up roll 156 to which it is secured by a key which may be manually rotated to advance the strip independently of a machine operation. The voucher strip 178 is drawn from a supply roll by feed rolls, fast with a gear 110 driven by a partially-toothed wheel 103 on the mainshaft 10, and co-operating with a pressure roller carried by a frame 115. Associated with the pressure rolls is a printing roll bearing constant matter and engaged by an inking roller. The strip emerges through a slot in the casing and the printed voucher is torn off. An ink-ribbon surrounds the type wheels, is tensioned by a lever 168, and is inked by a roller 171 on a slide 172. The inkribbon and the record strip are fed through oneway clutches by toothed wheels 148, 149 respectively, driven by a tooth 106 on the mainshaft. The impressions are effected by hammers 132, 133 controlled by cams 104, 105. The issue of a voucher may be prevented by depressing a hand lever 117 fast with a cam plate 118 which lifts a slide 121 carrying the ink roller for the constant matter, and rocks a lever 128 which depresses the frame 115 carrying the pressure roller and blocks the voucher hammer 133.
